Dc-Dc 400W 15A Step-Down Converter 10V-60V to 0-45V Constant Voltage and Constant Current Adjustable Power Supply Module

Main features of power module:

*10-60V wide input voltage, suitable for most power sources on the market as input sources.

*Output constant voltage and current, with continuously adjustable voltage and current. Can meet the needs of most electrical equipment.

*High output power, good ventilation, and natural heat dissipation can achieve 280W/12A (note that there are limitations on output power and output current).

*The module adopts a stepwise rectification scheme with extremely high efficiency, with an output voltage of over 10V and an efficiency of over 92% -96%,

*There is a constant current indicator when charging the battery. The charging status is clear at a glance.

*The input has a 15A fuse, and reversing the positive and negative poles of the input will not damage the power supply (it will burn the fuse and need to be replaced)

Module parameters

Product Model:SZ-BK0612

Module Name400w voltage reduction, constant voltage and constant current

Module nature:Non isolated voltage reduction module (BUCK)

Input voltage10.5-60V

Output voltage range:0-45V (must meet the voltage reduction condition, IN input multiplied by 0.8)

Output minimum voltage:0V(+1V)

Output maximum voltage:Approximately equal to input * 0.8 (for example, if the input is 40V, 40V * 0.8=32V, the maximum output voltage will be 32V, which will actually be slightly higher and reach around 34V.35)

Output constant current:0.2-15A (continuously adjustable, heat dissipation needs to be strengthened if it exceeds 12A)

Maximum output power:400W (requires adding a fan to forcibly dissipate heat from the heat sink and magnetic ring)

Continuous maximum operating power:280W (under ventilated environment)

Continuous maximum operating current:12A (under ventilated environment)

Input undervoltage protection:Yes, (the output is turned off when the input is below 10.5V, with an error of about 0.5V)

Input overvoltage protection:No (no overpressure allowed)

Operating Temperature-10~+85 degrees (strengthen heat dissipation when exceeding 65 degrees)

Working frequency:100KHz

Conversion efficiency:Up to 97% (efficiency is related to input and output voltage, current, and voltage difference)

Short circuit protection:Yes (constant current protection)

Reverse input protection:Yes (short circuit requires caution, reverse connection may burn the input fuse)

Output anti backflow:No (to charge the battery, output to inductive load, for example, to connect to a motor, anti backflow diode must be added)

Work indicator light:Yes (blue LED light)

Constant current indicator light:Yes, the CC indicator red light on the small board lights up during constant current operation, but there is no current output. This light does not light up during constant voltage operation

Wiring method:Comes with welding free 25A terminal block

Module size:Length 60, width 60mm, height 45mm

Net weight:170 grams Add packaging of 180 grams.

Packaging method:Independent paper box packaging.

Wiring:Input/IN "is the input. Output/OUT "is the output (indicated in Chinese)

Notes:

*It is strictly prohibited to connect the positive and negative poles of the input and output in reverse (reverse connection of the input will burn the fuse, and reverse connection of the output will damage the control board, which cannot be repaired and can only be replaced)

*The control panel has some rain proof adhesive, and if it is damaged, it can only be replaced. Mindful purchase

*When charging the battery and connecting the output to an inductive load, an anti backflow diode should be added to the output

Voltage and current regulation method:(Use tools such as a multimeter and a Phillips screwdriver)

Voltage regulationRotate the "CV" blue potentiometer on the power board according to your desired voltage, increase the voltage clockwise and decrease it counterclockwise

Output current regulation:Set the multimeter to the 20A or 10A current setting, adjust the voltage of the power supply to 5V, turn the constant current potentiometer "CC" counterclockwise for 20 turns, and set the current to the minimum. Use a multimeter to short-circuit the output, and then adjust the "CC" potentiometer clockwise to adjust the current to the desired value. (Note: When the constant current potentiometer "CC" is turned counterclockwise for 20 turns, the power supply may not have output voltage, as the current has been set to 0A.). Don't worry about him, increasing the current clockwise will produce output

The current detection of the module is low-end detection. Please do not short-circuit the input negative pole and the output negative pole directly with a wire. Short circuiting the negative pole power supply will not maintain a constant current, causing damage to the power supply and electrical equipment that require constant current.

The module is a voltage reducing power supply that can only reduce voltage but cannot increase voltage. The input voltage must be higher than the output voltage.
